Do you prefer your water bottle to be made of metal, plastic, glass, or something else? Straw or no straw? How big would you want it? Should the bottle taper down in the bottom, or do you think the sided should stay vertical? Are any of you one of the few people who would like that weird rectangular bottle? Or maybe one of those squishy fold up ones for travel? No handle, flip up handle, mug style handle, or little loop?

The perfect reusable water bottle is the one you already have 👏 stop buying more waterbottles
Metal, no straw, 0.75L, vertical and made in Europe. My current water bottle already has these properties, but its cap is a critical weakness, as it tends to spray some drops of water everywhere when you open it. So I’d like one with a better designed cap.
its like your penis. always spraying little spritz’s of liquid every time you flick It about.
1.25L stainless with a stainless/plastic lid. I use it a lot. Carry it everywhere. It’s dented and has stickers. Big drawback is where the lid seals there is a rubber gasket. That gasket is impossible to clean and molds over time. You can’t buy a new one. You have to purchase an entire new lid.
Whatever I have at hand is usually good enough. The lack of effort is it’s own advantage.
Currently I’ve got a 0.7L plastic slightly tapered without handle on my desk. Have a few of those that I got for free when buying protein powder in bulk.
Before that I had a standard 0.5L softdrink bottle i refilled instead of recycled. I don’t enjoy my water more despite the significant upgrade.
My perfect bottle has already been made. Sorry.
Can you share with the class?
Glass all the way.
A couple of these bad bois:

But in all seriousness:
Metal, insulated to keep it cool on hot days. No handle, it’s just in the way. Preferably a lid with a carabiner.
At home I use a 1L glass bottle with straight sides and a wide opening, metal lid and a neoprene sleeve. It’s cheap, easy to clean and does its job.
The obvious downside is that it’s heavy and can break if you drop it but I don’t travel a lot so that’s fine for me.
Vacuum insulated stainless. 40 oz. Can fit in a standard automobile cup holder. Has an AUTOSEAL lid.
I’ve been stuck on the “fits in a cupholder” part.
Love the Autoseal lid on my Contigo.
Yeti doesn’t have this?
With an Autoseal lid? Not to my knowledge.

Oh, so it looks like Contigo has a patent on the technology, which is probably why you can’t find an exact replacement with other companies.
Weirdly enough, Coleman has one with it. I have one of these, but it’s only 24oz. I also have a number of Contigos, both plastic and vacuum insulated. But none of the larger ones fit in a cup holder.
I love my Contigos, I have two that I’ve used for a decade. My dad got the one with the newer mechanism that’s MUCH easier to clean and I’ve been wanting one for years but I can’t justify the purchase when these still work great
Yes, they new ones are fantastic. The pre-EZ Clean era are a bit of a pain. I basically just put some soapy water in there, close them, and shake the shit out of them. Hope for the besr.
- Light Metal as long as it doesn’t end up making loud noises when bumped otherwise plastic
- No straw
- About 1.5 litres in volume
- A wide lid so it easy to clean with a primary lid above for drinking out of
- Nice pattern or large flat surface to draw/put stickers on
- Cylindrical up to wide lid
- squishy fold up ones are cool but not for day to use imo
- a handle/loop to attach it to my belt if I am out without a bag to carry it in
- insulated is good too
I want a goat story mug that accepts a contigo autoseal top. That curved shape fits perfectly on my hip and the contigo autoseal keeps my stupid ass out of trouble. I messaged a company that does food safe 3d prints and they quoted me $600 at the least and I don’t even really have the skills to 3d print something let alone select the right material, make sure the nozzle is lead free and has never been used for anything else, then sand and seal (and I’d have to make sure the threads still accepted the cup after sanding / sealing). Alas, it is but a dream.
-
glass, textured sides
-
swing top
-
1 quart min 1 litre maximum
-
tapered top, kicked bottom
-
basically this
I often kept some smaller versions if these in my fridge. I could easily grab a bottle of water whenever I wanted instead of filling it with plastic one time use bottles or cans of pop.
Can’t you just fill it from the tap?

20 ounce or 600mL (about the same), insulated, and easy to clean.
I like the Zojirushi, but the rubber parts get mouldy quick. Even if you clean it a couple times a day, people say no, you got to clean it more. No, I’m not cleaning the thing several times a day to keep it food safe. That’s just a losing battle.
Stanley makes a nice one, too (and green, so, bonus) and while it’s got a lot of complex moving parts, it’s very easy to clean with brushes. Mine fell wrong and the trigger popped out and there was so much mould inside, it was nasty. There’s no way to disassemble this part, but also, nothing in there touches the water. Still gross. I just threw it in the trash (it was unfixable anyway).
That’s WILD! Zojirushi makes good stuff, I love my rice cooker. But cleaning water bottle DAILY or it moulds?! I have a couple yeti bottles I use every day and bring everywhere and I soap-clean them uhhhhhh… sometimes. I just rinse my water bottles every so often, and wash my coffee bottle with soap every couple days.
I think I soap-wash my water bottles a few times monthly, and I’ve never had mould on them, ever!
Yeah, I dunno. I thought it it was just mould, it would wash off. I’ve taken some pretty harsh chemicals and scrubbers and they don’t give any. But the black dots that form on the rubber gaskets when they’re exposed to moisture weirds me out. If it’s not mould, even discolouration would be strange.

Insulated, metal, no plastic at all, rubber instead of plastic. 750ml to 1L Cap with a design thats easy to clean where the lips touch, and also not exposed to pets
Nalgenes are solid, usually polycarbonate so can handle a few knocks without disintegrating, but a point of contention is that they’re not insulated.
For summers I’ve got a 2L Wild Roots insulated flask that has withstood enough time on the jobsite to gain a few scratches, no serious dents as of yet
